Product Introduction

Weld material hydrogen testing can require flexible sample handling and reliable analysis across different hydrogen content levels. For welding blocks and other weld material samples, the sample size and required reporting unit can vary between testing tasks.

Our Solution:

The HUNO R3Hw addresses these requirements with a 30 mm sample tube, a programmed infrared heating system, a thermal conductivity detector and 10-point gas standard calibration. It supports hydrogen analysis in the range of 0.5–1000 ml/100g and can provide results in ppm or ml/100g, depending on the testing requirement.

Technical Parameters

Instrument Features

1. ISO 3690 and AWS A4.3 Compliance: The HUNO R3Hw complies with ISO 3690 and AWS A4.3 requirements for weld material hydrogen analysis.

2. Flexible Result Output: Analysis results can be output in either ppm or ml/100g according to the testing requirement.

3. Automated Heating and Analysis: The infrared furnace can heat to 900°C and provides programmed heating for the analysis process.

4. Large Sample Capacity: The sample tube has a diameter of 30 mm and supports welding blocks of different sizes, with a maximum sample weight of 200 g.

5. Pre-Stored Sample Weight: The weight of the sample to be tested can be pre-stored in the system.

6. Searchable Data Management: The system supports searchable data storage and analysis result evaluation.

7. FTP / LAN Data Transfer: Analysis data can be transferred through FTP or LAN.

Daily Maintenance

1. O-Ring and Catalytic Furnace Maintenance — O-rings should be coated with vacuum silicone grease during replacement. If CuO in the catalytic furnace needs to be replaced, it should be replaced according to the maintenance requirement.

2. Hydrogen Electrode Inspection — If unstable results occur, check whether the hydrogen electrode is making proper contact and whether oxidation or other conditions are affecting the electrode.

3. Gas Flow Check — When the hydrogen analyzer shows unstable performance, check whether the gas flow is sufficient and whether the carrier gas flow is appropriate.

4. Leakage Inspection — The equipment includes a system leakage inspection function. The operator can select the main valve, perform leak detection and inspect the sealing valves through the system.

Quality & Standards

Standards Compliance: The HUNO R3Hw complies with ISO 3690 and AWS A4.3 standards.

Gas Standard Calibration: The analyzer uses 10-point gas standard sample calibration to cover applications across high and low hydrogen content ranges.

Quality Management: PENY strictly controls raw materials, production processes, and quality inspection under an ISO 9001-certified quality management system.

Customer Case

Institute of Metal Research, Chinese Academy of Sciences

The Institute of Metal Research, Chinese Academy of Sciences requires high-precision carbon, sulfur, oxygen, nitrogen, and hydrogen analysis techniques to support research in multiple new material research fields. After communication and an on-site investigation, the institute purchased one carbon sulfur analyzer and one OHN analyzer from PENY.

After the instruments were delivered to the institute and installed and adjusted, the institute highly appreciated the two analyzers.

Packaging & Delivery

Packaging: PENY uses professional fumigation-free export wooden boxes with high strength and impact resistance to help protect the analyzer during transportation.

Delivery Time: Approximately 30 days.

Warranty & After-Sales Service: PENY provides a 1-year warranty for all products and 24-hour, 7-day after-sales service.

FAQ

Q: Do you sell spare parts and consumables for elemental analyzers?
A: Yes, we sell spare parts and consumables for elemental analyzers at reasonable prices. If you have any requirements, please feel free to contact us.

Q: What materials is the analyzer packaged with?
A: Our elemental analyzer is packaged with a packing list, factory inspection report, and user manual before leaving the factory. If you need any additional certificates, please feel free to let us know.

Q: What is the detection limit of the HUNO R3Hw?
A: The HUNO R3Hw can detect low levels of weld material hydrogen, with a detection limit of less than 50 ppb.

Q: How does the HUNO R3Hw correspond to ISO 3690?
A: The HUNO R3Hw complies with ISO 3690 and AWS A4.3 standards for weld material hydrogen analysis.

Q: How can we know if we need a regulated power supply?
A: The analyzer requires a stable voltage supply to ensure stable operation. Before use, you can test the power supply with a professional tool such as a digital multimeter. If the power supply is unstable, a regulated power supply is recommended.
